Some people believe
that sightings of a sea monster may have just been confused with the
existence of the recently famous, and real, manatee who was also given the nickname of Chessie.
The manatee from Florida was first captured in the waters of the Chesapeake
Bay in the fall of 1994. Chessie the manatee was then equipped by scientists
with a satelite-monitored radio tag and shipped back to Florida.

The
manatee has been tracked by the U.S. Geological Survey's Sirenia Project. The
monitoring of this manatee has shown the animal to have traveled as far north as
Rhode Island. The manatee's tracking device became unattached
and was found near Connecticut in August of 1995. The manatee was later spotted
in Florida and retagged with a new tracking device in February of
1996.

The journeys of Chessie the manatee have sparked
the desire of scientists to track other manatees and their travel patterns. As
of 1996, seventeen manatees had been radio-tagged, but non travelled to any
waters north of Georgia.

Some other reasons why Chessie may not exist:

The Chesapeake Bay shallower than other bodies of water said to contain odd sea creatures:
